Chem Ch 11 - Gases
| Term | Definition |
|---|---|
| absolute zero | the coldest temperature possible at which molecular motion stops. (0 K, -273 C, -459 F) |
| atmosphere (atm) | the average pressure at sea level, 101,325 Pa (760 mmHg) |
| Avogadro's law | a law stating that the volume (V) of a gas and the amount of the gas in moles (n) are directly proportional |
| Boyle's Law | a law maintaining that the volume (V) of a gas and its pressure (P) are inversely proportional |
| Charles's law | a law stating that the volume (V) of a gas and its temperature (T) expressed in kelvins are directly proportional |
| combined gas law | a law that combines Boyle's law and Charles's law; it is used to calculate how a property of a gas (P, V, or T) changes when two other properties are changed at the same time |
| Dalton's law of partial pressures | a law stating that the sum of the partial pressures of each component in a gas mixture equals the total pressure |
| hypoxia | a shortage of oxygen in the tissues of the body |
| ideal gas constant (R) | the proportionality constant in the ideal gas law. |
| ideal gas law | A law that combines the four measured properties of a gas: PV=nRT |
| kinetic molecular theory | a simple model for gases that predicts the behavior of most gases under many conditions |
| millimeter of mercury (MM Hg) | a unit of pressure that originates from the method used to measure pressure with a barometer. also called a torr. |
| molar volume | volume occupied by one mole of gas. under standard temperature and pressure conditions the molar volume of ideal gas is 22.5 L. |
| nitrogen narcosis | an increase in nitrogen concentration in bodily tissues and fluids that results in feelings of drunkenness |
| oxygen toxicity | the result of increased oxygen concentration in bodily tissues |
| partial pressure | the pressure due to any individual component in a gas mixture |
| pascal (Pa) | the SI unit of pressure, defined as 1 newton per square meter |
| pounds per square inch (psi) | a unit of pressure. 1 atm = 14.7 psi |
| pressure | the force exerted per unit area by gaseous molecules as they collide with the surfaces around them |
| Standard Temperature and Pressure (STP) | conditions often assumed in calculations involving gases: T= 0 C (273 K) and P= 1 atm |
| torr | a unit of pressure named after the Italian physicist Evangelista Torricelli; also called a millimeter of mercury |
| vapor pressure | the partial pressure of a vapor in dynamic equilibrium |
| Gay-Lussac's Law | the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant |
